TDA7854 Datasheet PDF - ST Microelectronics

●Description

●The TDA7854 is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt 25 package designed for high power car radio. The fully complementary P-Channel/N Channel output structure allows a rail to rail output voltage swing which, combined with high output current and minimized saturation losses sets new power references in the car-radio field,

●with unparalleled distortion performances.
